Sea of Silver Light  - Tad Williams 3.5 stars, really, but I'm rounding up because of the overall strength of the series.

Sea of Silver Light is a very slow starter - and a slow finisher, for that matter. Like the other Otherland books, it's far longer than it needs to be; I genuinely feel that it could be cut down by two thirds without losing much of value. Doubtless, die-hard fans would disagree, and this is the main reason why I can't count myself among them. Still, a very enjoyable and appropriately immersive series.
